Round Rail products typically use Thomson™ shafting and matching ball bushings for motion with minimal friction during travel.  Load capability of such products is usually excellent with very good straightness of travel.  Butt joining of shafting allows for virtually unlimited travel lengths.

Shafting options include Thomson 60 Case™, Stainless Steel and Chrome Plated Steel to just name a few.  If alternate shaft material is desired, whether standard or custom, we can satisfy your needs.

The ball bushings are available in standard, adjustable and preloaded versions.  Seals are available as are resin cages.  With SMI™ leveraging an extensive supplier mix including NB, Thomson, IKO, Bosch Rexroth and others, a myriad of options are available to our customers to meet any application.
